Introduction
I am a Ph.D. Candidate in the Department of Agricultural, Food, and Resource Economics at Michigan State University. My research interests are in the intersection of agricultural and development economics, applied microeconometrics, and impact evaluation.

We examine factors affecting the adoption of improved cassava varieties of 217 households in the Cauca Department in southwest Colombia. Using DNA fingerprinting through Single Nucleotide Polymorphisms (SNPs), we identified different cultivars in farmers fields. We also used this information to remove possible bias in the adoption model that could...

Multivariate and ordered Probit models were used to study the determinants of the adoption and extent of adoption of agronomic practices among cacao farmers in Nariño, Colombia, with data from 353 farmers in the mountain region. Results suggest that farmers' adoption decisions are made on a joint basis, further validating the use of a multivariate...
Article
Full-text available
Using a double-hurdle approach, we assess factors associated with the extent of participation in the rice market with data for small-scale farmers drawn from a nationally representative dataset. The results suggest that larger endowments and assets, animal farming and commercialization, and alternative off-farm income make farmers less likely to pa...

We study the effect of temperature on students' performance and how changes in the incentives to study alter this impact in the context of high-school exit exams in Colombia. We show that temperature increases have a negative impact on exam scores, particularly among urban students. Conversely, rural students exhibit slightly positive effects. Leve...

The adoption of higher-nutrient grass varieties, such as Brachiaria, offers long-term economic benefits for ranchers while enhancing soil health and pasture productivity in Latin America's lowland climates. Despite widespread adoption, the field-level impacts remain largely unexplored. This study, focusing on Colombia's largest beef-producing regio...
Article
Full-text available
Rice research and technology development in Latin America has increased yields and offered the opportunity for several countries to contribute to global food security by becoming net exporters of this cereal. In spite of the broad availability of rice technologies in the region, rice yields remain substantially low in countries like Bolivia. This s...
Article
Full-text available
Potato is a traditional and economically important crop for farmers in the high mountains of Nariño (Colombia). However, its productivity growth is weakening, injuring farmers’ livelihoods. We hypothesize that an in-depth study of farm typologies and their relationship with productive efficiency could prove helpful in delivering recommendations for...
Article
Full-text available
Pitfall trapping remains one of the most frequently used methods to assess ground-active arthropods’ diversity and density. Yet, one of its main drawbacks, the possibility that repeated collecting may affect the study objects’ population, has not been formally tested. We studied the effect of a yearlong epigeal pitfall trapping exercise with 22 for...
Article
Full-text available
Bolivia has disseminated several improved technologies in the rice sector, but the average rice productivity in the country is far below the average trend in Latin America in recent years. Although the economic literature has highlighted the role of agricultural technology adoption in increasing agricultural productivity, gaps remain in understandi...
Article
Full-text available
Introduction. Long-term genetic improvement efforts in Latin America aimed to ameliorate peach-palm fruit farmers’ technical capacities and livelihoods have proven to be ineffective. Although experts agree this is partly the result of large uncertainty regarding consumer preferences, such research remains as virtually nonexistent. Objective. To ide...
Data
This dataset provides a description of cassava farmers collected in the Colombian Caribbean Region in 2017. The survey was implemented using a structured questionnaire administered among 395 households, collecting data at both household and plot level. Survey information includes household socio-demographic characteristics, cassava management pract...
Thesis
The adoption of agricultural technologies, and specially modern improved ricevarieties (MIV) are significantly low in Bolivia with respect to the rest of LatinAmerican countries. With a nationally representative sample of Bolivian rice grow-ers the determinants of adopting jointly complementary agricultural technologiesare explored. Results reveal...

El sector arrocero en Latinoamérica ha experimentado cambios significativos durante los últimos 40 años, mostrando incrementos en los rendimientos que llegan a ser del triple, en promedio. Sin embargo, este no ha sido el caso de Bolivia. Tomando en cuenta la posible brecha tecnológica afrontada por el sector arrocero boliviano, este documento anali...
